"Several issues have been found in mupdf, a lightweight PDF viewer.

The issues could be exploited by crafted PDF files that result in
denial of service by heap-based buffer overflows, segmentation faults
or out of bound reads.

For Debian 9 stretch, these problems have been fixed in version
1.9a+ds1-4+deb9u5.

We recommend that you upgrade your mupdf packages.

For the detailed security status of mupdf please refer to its security
tracker page at: https://security-tracker.debian.org/tracker/mupdf

block directly from the DLA security advisory. Tenable has attempted
